The Cecilia McDowall Anthem 'Now is the Time' is soon to be published by OUP. See global.oup.com/academic/product/now-is-the-time-9780193512603?q=Cecilia%20mcdowall&lang=en&cc=gb
I should remind you that although you are allowed to keep the copy of 'Now is the Time' given to you on the day, the license for it expires once it has been published. If you wish to perform it once it has been published you will have to purchase an official copy from OUP. You are not required to destroy your copy from the day.
